Darik's Boot and Nuke, also known as DBAN / ˈdiːbæn /, is a free and open-source project hosted on SourceForge. [2] The program is designed to securely erase a hard disk until its data is permanently removed and no longer recoverable, which is achieved by overwriting the data with pseudorandom numbers generated by Mersenne Twister or ISAAC.
Gutmann method. The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files. Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.
Eraser securely erases data by overwriting it such that the data is irrecoverable. [1] It supports a variety of data destruction standards, including British HMG IS5 (Infosec Standard 5), American DoD 5220.22-M , and the Gutmann method which features a 35-pass overwrite.
HDDerase is a freeware utility that securely erases data on hard drives using the Secure Erase unit command built into the firmware of Parallel ATA and Serial ATA drives manufactured after 2001. [ 1] HDDerase was developed by the Center for Magnetic Recording Research at the University of California, San Diego. HDDerase is designed for command ...
